摘　　要：甲板货船主要是甲板载货,具有开敞的载货甲板、卸货方便等特点。这类船长深比和宽深比较大,往往船体变形较大,总纵强度的校核和挠度变形必须给与足够的重视。文章以NAPA软件为平台,开发了一套甲板货船总纵强度校核系统,实现了船体挠度计算和船体变形后总纵强度校核,供图纸设计、船舶检验等相关技术人员参考。Deck cargo ship is self-navigated and mainly transports dry, mixed, bulk cargo on deck. This ship has open cargo deck, and unloading conveniently. However, the length depth ratio of such ship,especially breath depth ratio are larger than the current "standard"(with scale applicable to the scope of the flat structure). Its deformation is often larger, the longitudinal strength and deflection must be given adequate attention. This article is based on NAPA software development platform, using NAPA BASIC language to develop a set of checking system about the longitudinal strength of deck cargo ship considering deflection and taking into account the deflection and the longitudinal strength check for the reference of relevant technicians such as drawing design and ship inspection.
